Mike Cogozzo you need to remove the "choke" around the inner door. Open the door and locate the plastic seal that goes all the way around the inner door. This is the "choke" and it's clipped in on both the inside and the outside, all the way around the door. You will need to use a small putty knife or a small flat head screw driver and pry under the choke all the way around to unclip it. Once you have that part off, removethe 2 screws going into the door handle.

for PVM9179SF1SS door handle replacement .. even after i remove the choke, the screws are under a grate frame .. so not accessible. i tried removed the 3 screws holding the grate frame but still it would not budge. any suggestions ?

Since this answer is incomplete, I will add this one point. There are little plastic clips attached to the outer door that hold the grate frame in place. If you look around outer edge of the grate frame with a flashlight you will see them. If you unhook these clips from the grate frame, the grate frame will, not easily, pull away from the outer door and that will expose the handle screws. Be careful, because the grate frame will swing on the door hinges, but there is nothing holding it in place once you unclip it from the outer door so if you let it hang there while you work, it may fall off.
